Sequence Objects

In bi-directional Enterprise Replication, if you
replicate tables using sequence objects for update, insert, or delete
operations, the same sequence values might be generated on different
servers at the same time, leading to conflicts.

To avoid this problem, define sequence objects on each server so
that the ranges of generated sequence values are distinct. For more
information about the CREATE SEQUENCE and ALTER SEQUENCE statements
of SQL, see the IBM®
Informix® Guide to SQL: Syntax.
